Abstract

본 발명은 음성 인식 기능을 이용하여 평상시의 운전자의 음성을 전기신호로 변환하여 메모리에 저장시키고, 음주운전시의 운전자 음성 신호를 정상 음성 신호와 비교함으로써 운전자가 음주를 하였다면 자동차의 시동이 걸리지 않도록 하여 음주운전에 의한 사고를 미연에 방지하기 위한 음성 인식 기능을 이용한 음주운전방지 장치 및 방법에 관한 것으로, 운전자의 정상 음성신호를 전기 신호로 변환하여 이를 메모리에 미리 저장시켜 놓으며, 다음에 운전자의 음성 신호를 전기적인 신호로 변환하여 메모리에 저장된 정상 음성 신호와 비교하며, 상기 정상 음성 신호와 다음의 음성신호의 차가 일정값을 초과하면 운전자의 상태가 정상적인 상태가 아닌 것으로 판단하고(음주상태로 판단), 운전자가 시동키이를 돌려도 스타트 모터의 전원을 자동으로 차단함으로써 음주 운전자가 자동차를 주행시키지 못하도록 하는 효과를 가진다.The present invention converts the driver's voice into an electrical signal using a voice recognition function and stores it in the memory, and compares the driver's voice signal with the normal voice signal during drunk driving so that the driver does not start the car if the driver drank. The present invention relates to a drunk driving prevention device and a method using a voice recognition function to prevent accidents caused by drunk driving, and converts a driver's normal voice signal into an electric signal and stores it in a memory in advance. The voice signal is converted into an electrical signal and compared with the normal voice signal stored in the memory. When the difference between the normal voice signal and the next voice signal exceeds a predetermined value, it is determined that the driver's state is not normal (into a drinking state). Judgment), even if the driver turns the ignition key, By blocking has an effect that prevents drunk drivers are not driving the car.
